Chain-Smoking Robot Destroys Its 'Lungs' for Science

Going all the way back to poor John Henry, robots have proven that they can outperform humans. And now, researchers have designed a robot that would leave Patty and Selma gasping for air. Researchers studying the effects of cigarette smoke on our lungs have struggled to find a good model for their research. Most animals used for research breathe only through their noses, it's difficult to expose cell cultures to realistic smoke, and there's often too much variability between human test su
